<h1>字符串函数 - strcmpi</h1>


  <p>原型：extern int stricmp(char *s1,char * s2);</p>
        
  <p>用法：#include &lt;string.h></p>
  
  <p>功能：比较字符串s1和s2，但不区分字母的大小写。</p>
  
  <p>说明：strcmpi是到stricmp的宏定义，实际未提供此函数。</p>
        当s1&lt;s2时，返回值&lt;0
        当s1=s2时，返回值=0
        当s1>s2时，返回值>0
  
  举例：<pre><code class="language-c">

      // stricmp.c
      
      #include &lt;syslib.h>
      #include &lt;string.h>

      main()
      {
        char *s1="Hello, Programmers!";
        char *s2="Hello, programmers!";
        int r;
        
        clrscr();
        
        r=stricmp(s1,s2);
        if(!r)
          printf("s1 and s2 are identical");
        else
        if(r<0)
          printf("s1 less than s2");
        else
          printf("s1 greater than s2");
        

        getchar();
        return 0;
      }
